Today, a new research group has been
announced that will focus on furthering our understanding of the efficacy and
impacts of ocean iron fertilization (OIF).
An initial group of twelve universities
and research centers from around the world have come together to found the ISIS
(in situ iron studies) Consortium. Its mission is to explore the potential impact... >>>

KALW Crosscurrents is doing an interview of me talking about OIF, geoengineering and the recent Asilomar conference for Earth Day. Kudos to them for being willing to take on a complex issue, particularly on a sacred day for environmentalists. Could we be getting closer to the day that those... >>>

An article looks at the positive benefits of ash to the nutrient cycle in the ocean... There are a few good papers on this, including Frogner, et al 2001 in Geology.
"By now, you may know that airborne ash from the volcano that erupted
through... >>>

In case the world can't contain its carbon emissions, among
geoengineering fixes Dan Whaley, founder and chief executive of
California-based Climos, hopes tiny plankton that live on the
ocean surface can be used to absorb CO2 as they grow.
"These are not silver bullet solutions, but things that
might take the edge off," he told Reuters. "What is the risk of
doing nothing? We think it's so extraordinary it's apocalyptic.
These geoengineering projects, the research into this, is an
exercise to reduce future risk."

Reasonably thoughtful overview of the field by The Atlantic.
"If Martin’s ideas are sound, Climos could in effect become the world’s
gardener by seeding Antarctic waters with iron and creating vast,
rapidly growing offshore forests to replace the ones that no longer
exist on land."

Climos is exploring techniques for naturally removing large amounts of CO2 from the atmosphere. One such technique, Ocean Iron Fertilization (OIF), is based on a natural process that is one of the Earth's primary natural mechanisms to remove carbon dioxide. It has very high mitigation potential... >>>

With significant reductions in emissions likely to require decades and the impacts of
projected climate change likely to become more and more severe, proposals for taking
deliberate action to counterbalance global warming have been proposed as an important
complement to reducing emissions. While...
